Answer:

x=-1

Step-by-step explanation:

-4x+7=11

Subtract 7 from both sides:

-4x+7-7=11-7

-4x=4

Divide both sides by -4:

\frac{-4x}{-4}=\frac{4}{-4}

x=-1

X is proportional to ✓y where y>0 .
DENIUS [597]

Answer:

20%

Step-by-step explanation:

x = k√y

Increase y by 44%. y becomes 1.44y.

x = k√(1.44y)

x = 1.2k√y

x went from k√y to 1.2k√y.

(1.2k√y)/(k√y) = 1.2

x is now 1.2 times greater than it was, so the increase in x is 20%.

Answer: 20%
